C-201 Electrical Systems 1 – SACA Certification – End Term
Exam A+ Graded
can you define and test a ground? - ✔✔a ground is a point in the circuit that is connected to the earth.
you can use a multimeter-If the resistance is too high, it may indicate that the ground connection is not
providing adequate protection
electrical safety rules - ✔✔1.Always use a circuit tester or voltage detector to check that a circuit is de-
energized before working on it.
electrical safety rule - ✔✔Never touch electrical wiring or equipment with wet hands or while standing
on a wet surface.
electrical safety rule - ✔✔Do not operate electrical equipment that is damaged, frayed, or otherwise in
poor condition.
electrical safety rule - ✔✔Use the correct fuse or circuit breaker for the circuit you are working on.
electrical safety rule - ✔✔Never remove or bypass the grounding prong on a plug.
Electrical Safety - ✔✔Do not use extension cords or multiple outlet adapters that are not rated for the
equipment you are using.
electrical safety - ✔✔Do not overload circuits by plugging in too many devices or using high-powered
equipment.
electrical safety - ✔✔Do not use electrical equipment in wet or damp conditions unless it is specifically
designed for that purpose.
electrical safety - ✔✔Use properly rated and properly installed surge protectors for sensitive electronic
equipment.
, electrical safety - ✔✔Always follow the manufacturer's instructions for using electrical equipment.
purpose of lockout tag out - ✔✔to prevent unexpected energization or startup of machinery or
equipment while it is being serviced or repaired.
state the two types of electrical current - ✔✔AC and DC
how to use a circuit tester - ✔✔To test a circuit, first locate the circuit breaker or fuse that controls the
circuit you want to test. Then, using the circuit tester, touch the red probe to the live wire and the black
probe to the neutral or ground wire.
what is a power source - ✔✔The power source is the source of electrical energy for the circuit. It can be
a battery, a generator, or a power outlet. The power source provides the electrical current that flows
through the circuit.
what is a conductor - ✔✔The conductor is a material that allows electricity to flow through it, such as a
wire. The conductor carries the electrical current from the power source to the load.
what is a load - ✔✔The load is the device or appliance that is being powered by the circuit. It can be a
light bulb, a motor, or any other device that uses electricity. The load converts the electrical energy from
the circuit into some other form of energy, such as light or motion.
what is a switch - ✔✔The switch is a device that is used to control the flow of electrical current in the
circuit. It can be used to turn the circuit on or off, allowing the load to be powered or de-powered as
needed.
two types of power supplies and schematic symbol - ✔✔AC and DC
be able to interperate an electrical schematic which includes symbols - ✔✔on youtube look up
engineering mindset- Single Phase Electricity Explained - wiring diagram energy meter
resistor symbol - ✔✔
